Hey! I haven't traveled to Ross with my dog, but I have taken my dogs in and out of the US on a few occasions. Make sure the dog meets the import requirements of Saint Kitts and Nevis first and foremost. If it is a small dog it can probably travel under your seat. If it is a large dog (assuming it is not an ESA or service animal), it will have to fly under the plane. There are restrictions for flying to so make sure you check out airlines and which will work best for you and your pup.
